80 300 Tph Stone Crushing Production Line

80-100 tph crushing plant usually has two types of crushing plant: 80-100 tph jaw & impact crushing plant and 80-100 tph jaw & cone crushing plant.The 80-100 tph jaw & impact crushing plant includes vibrating feeder gzd960x3800, jaw crusher pe600x900, impact crusher pf1214, vibrating screen 3yzs1848, belt conveyors and centrally electric controlling system, etc.The designed capacity is from 80t/h to 100t/h.To meet customer's specific requirement, we can also add other equipments such as cone crusher, dust catcher on the crushing plant.The 250-300 tph jaw & cone crushing plant includes vibrating feeder gzd1300x4900, jaw crusher pe900x1200, cone crusher zys51-b,zys51-d, vibrating screen 3yzs1860, belt conveyor and centrally electric controlling system, etc.This designed capacity is from 50t/h to 500t/h.To meet customer's specific requirement, we can also add other equipments such as impact crusher, dust catcher on the crushing plant.Process of 250-300 tph jaw & cone crushing plant: big materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing.After first crushing, the material will transferred to cone crusher by belt conveyor for secondary crush; the crushed materials will then transferred to vibrating screen for separating.After being separated, the parts that can meet standard will be taken away as final products, while the other parts will be returned to impact crusher, thus forming a closed circuit.Size of final products can be combined and graded according to customer's specific requirement.We can also equip dust catcher system to protect environment.The customer's mine deposit is wide and well suited to large-scale open-pit mining at a planned ore: waste ratio of about 1:4.Test mining and pilot scale beneficiation showed that the ore can be recovered by traditional methods, with high recoveries at low unit costs.The feasibility study mine planning covers the period 2009-2017 and envisages three pits with the largest on the north side of the deposit.Laiva will mine 10-m-high waste benches and 5-m ore benches using pattern blasting.The 200-mt and smaller excavators will selectively load to 100-mt-capacity haul trucks.Nordic mines personnel will do the mining with help from specialist contractors, said nilsson.The processing element of the feasibility study and financial calculations were carried out by outotec.Two 250 mt/hour outotec autogenous mills will grind to 175 micron with cone crushers in circuit for handling oversize.A 170-kw sbm grinding mill will regrind part of the output to 45 micron.A mobile crusher has been used for mill test feed but installation of the metso stationary crushers was the next job on the schedule at the time of writing.Flash flotation will be used to extract 80% of the sulphide material for storage in a lined pond.The regrind milling circuit will separate out a small fraction suitable for gravity separation in a falcon or knelson concentrator and the overflow will go to the cil tanks.An inco process cyanide destruction system will treat the outflow and the tails will go to a paste plant that will also recover water for recycling.The end-product will be dore gold, with a target initial production rate of 118,000 oz/y based on 86% gold recovery to be followed by an expansion.
